'This invention relates to improvements in'poll'ring deYices. Y

I It's one ofthe objects of this invention to provide an 'improved metalpouring device,

of the 'type which issuspended' from an" overhead crane, in which theraising and lowering of the ladle, to'adjust'it to moldsofvariousjheights;is'accomplished in a simple and novel manner." A"further "obje t of this invention is to provide a pouring device inwhich a hand wheel is'utilized for accomplishing both the raising andlowering, said hand wheel being o geared to themovable member as topermit raising of the ladle with the'minimum amount of effort. v

'Itis a further object of thisinvention to provide a" devi'ce "of theclass described in which the ladle maybe lowered either rapid- 2 0 ly bymeans of gravity or'slowly by hand.

; A further object ofthis-i'nvention is to provide means forautomatically locking said ladle in, any desired position against I ufurther downward movement by gravity.

Adurther object" of this invention is to provide an improvedpouring'devicewhich is comparatively simple in construction, and whichcan readily be operated by one'man. With the above and other-objects inview, the invention consists of the improved pour ing devi ce, and allits parts and combinations, asiset'forth in the claims, and allequivalents thereof.

In the accompanying drawings, illustrat- 1 ?ing. one complete embodimentof thepreferred form'of the invention, in which the same referencenumerals designate the same parts in all of theviewsz" Fig. 1 is a frontelevation of the device; Fig. 2 is aside view thereof; YI'Fig.j3jis-anenlarged detail front view of the portion of the'deviceadjacent the hand i bearings 32 within the bearing portions 30wheehparts b'eing broken away; i 'Figz t is a side viewot the portion ofthe device shown in Fig. 3;

Fig.5 is a sectional view taken on'line 60 and tween the Fig. 7 is asectional detail view of the clutch mechanism.

Referringto the drawings, the upper frame comprises a pair of rods 10having their upper ends secured to a cross piece 11 and having theirlower ends slidable in openings in short cross pieces 12. Rods 13 havetheir lower ends secured to the cross pieces 12 and have their upperends slidable in openings .in the cross piece 11. The extremeupper Aninverted elongated U-shaped member 17 has its upper end secured tothecross piece 11 by a bolt 18 and has its lower ends curved to extendaround bolts 19 of the lower frame. The saidlower ends of the U-shapedmember are secured by bolts 20 to the lower ends of the rods 10. p Thelower frame comprises a pair of spaced apart plates 22. A rack bar 23,having teeth 24 extending along one side thereof, is slidably positionedbetween said plates 22, the outer side of said rack bar engagingfriction reducing rollers 25 which are rotatably mounted between theplates 22.

Plates 26, which are secured to each side of i V the rack bar at itsupper end extend beyond the edges of said rack bar and slidably embraeethe sides of the U-shaped member17;

A roller 27 is rotatably carried between said plates 26 at their extremeupper ends. The lower end of the rack bar carries a bail 28 within whicha ladle 29 is pivotally mounted.

J ournaled through bearing portions 30 of the plates 22 is a tubularshaft 31. Roller surround said shaft. A pinion'33, which is keyed to theshaft 31'is positioned be- 7 plates 22 and engages the teeth 24 of therack bar 23. A gear housing 34, having a removable cover 35, extendsfrom one of the bearing portions 30.

Journaled in roller bearings 36, within responding end of the tubularshaft 31, one

of said ends being within the'housing 34. On'said end a gear 38 isrigidly. niounted, the said' meshing with larger gears 39 The gears 39are loosely mounted on shafts 40 which are connected between a plate 41and the irmelr'ffaceof a plate 41". Hubs'43' of the gears 39: are formedwith-teeth 44 which en 'a 'e the teeth 45 of a rin ear 42.

C C b D The ring gear is rigidly connectedjto the side of the casing.The plate 41' is integral with a hub member .42, thelatter being keyedto the tubular shaft 31." Side pieces" on the wheel hub 52 will. engagethe lugg56 on the collar 55 as shownby the dotted lines in Fig. 3 tocause rotation ofthe shaft-37. As soon as the manipulation ofthehand.

43f connect the plate 41 and the plate 41;

A disk clutch 46 having threaded huh portion 47 is keyed to the outerend of the shaft 37 Theou'ter face of said clutch carries aifibre'dish48, and adjacent said disk a washer. 49 s loosely positioned.Loosely surrounding the hub portion 47. ad acent the washer is a ratchet50 having oilgrooves 51 on itsputerface. Threaded on-the hub-47 of theclutch is the hub 52 ofa hand wheel 53, said huh 52 having a lugprojecting outwar dly therefrom. Keyed. to the extreme outer'end of theshaft-37 is a collar 55 carrying a laterally extending lug 56kwhich isadapted to engage-the lug; 54. A nut 57 holds said collar on the shaft.'Rods 58, extending through the. gear housing,.nuts 60 beingt-hreadedon; each side of said lugs.

said. rods extend through abar 61 and have 5.0, by .a spring .65,

nuts 62 threaded thereon. The bar 61 carries a; pin 63 onwhich a dog 64is ,loosely .mounted, the said dog being normally-held inengagement withthe teeth of the ratchet A lever 66; which has its H1118? end looselymounted on the p n 63 'is adapted to engage an extension 67 of the. e sen dog 64 to movethe latter out of e withthe ratchet. I f 'In operationof. the device, when. it is pagainst the clutch 46 as shown in 5, thedog 64 sliding over the teeth of the ratchet.

hen the hand wheel is thus turned, the

lugs 54 and 56 are out of engagement as shown by the full fines in Fig.3, the rota tion of the shaft 37 being caused by frictional engagementbetween the handwheel hub 52, the ratchet 50 and the clutch CllSlil 45,the latter being in keyed'connect1o1rw1th 53.

thesliaft 87. Rotation-of the shaft-87v causes rotation of the gear 38;and the gears 39 aml 43, the gears 43j'traveling aroundwithinthestationary ring gear 42. Asthe'latter gears 39 and 43 revolve the plates41. and 41. are also rotated as -1 s the hub port on 42 of the theplates22 havfeone end extending. through lugs 59 of,

The other. ends of.

,said shaft is rotated and also the pinion 33,

the pinion engaging the teeth of the rack bar 23and moving thesameupwardly. The gear arrangement above described "permits raising ofthe ladlewith a minimumamount,

of effort.

. To "slowly lower the; rack-hanthe hand wheel is turned'insacounterclockwise directime, its hub 52- beingthreadedaway from 'theratchet 50 as shown in Fig. 7 just far enough so-th-atthe ratchetdoesnot engage the clutch 4 6.. s The loosely mounted ratchet will then beheld stationary the'dog 64 and the lug 54 wheel is stopped the weightof. the ladle the clutch disk 46 will engage the ratchet 48 whichis-locked by the dog 64,.tov prevent,

downward movement of the ladle. by gravity} Thus the clutch mechanism;will. 'automa'tir cally act as a brake .toholdtheladle'in any;

desired position;

If it is desired to by gravity the'lever 66 is operated to disengage thedog 64; from the-ratchet. .Uponreleasing the lever, the spring 65fwillbring the dogback into engagement. with the ratchet andthe clutch willimmediately act to hold the-ladle andrack barin the desired loweredposition.
